USS Moray (SS-300) Photogrammetry Model

[beldridg]

Cool -- would you be able to provide some details on the equipments you used?

Camera was a Sony a7rIV in a Nauticam housing with a 28mm lens and the Nauticam WWL1-B wide angle wet lens. Lighting was dual Kendal 18k video lights. Processing was done in Metashape.

The next likely question of video vs stills would take more time to explain and too much to post here.

Wide angle lenses have two advantages: (1) getting closer to the subject to light while (2) getting enough of the subject in a frame to avoid needing even more photos.

This preso might answer some additional questions:

Thanks! It was an epic project that has been on the list for a very long time. Just getting approvals to dive the wreck is a big undertaking.
